DIN CEN/TS 17951:2024-11

This CEN Technical Specification specifies the lighting and operating requirements for the application of adaptive emergency escape lighting systems that can interact with management and control systems or be provided with functionality to modify the operation of emergency escape lighting according to situational requirements, in terms of luminous flux output, escape directions and the characteristics and meaning of emergency escape lighting. The situational requirements can require the involvement and interaction with components and systems other than emergency escape lighting systems. Requirements for these components or systems are not part of this document. The purpose of lighting escape and rescue routes is to make it easier for people to leave a location safely by ensuring adequate visibility and orientation on escape and rescue routes through a combination of luminaires and signs designed to meet the specified conditions. Adaptive emergency escape lighting systems (AEELS) can be used to change the escape route guidance and increase the visibility of signage depending on the location of a specific hazard by using directional safety signs that can be controlled to change the escape route guidance information and lead people away from an escape route that has become unusable. This document (CEN/TS 17951) has been prepared by Technical Committee CEN/TC 169 "Light and lighting", the secretariat of which is held by DIN (Germany). The responsible national standardization committee is Working Committee NA 058-00-16 AA "Notbeleuchtung" ("Emergency lighting") at DIN Standards Committee Lighting Technology (FNL).
